Drive battery heating control
When main vehicle 11 is in low temperature environment, the temperature of driving battery 15 reduces, and drives the input of battery 15 It may be decreased with output performance (can receive electric power and exportable electric power).In such a state, when user attempts driving main vehicle When 11, the electric power of sufficient amount cannot be supplied from driving battery 15 to the 2nd MG 16C, and may be decreased using the 2nd MG The performance of the electric vehicle of 16C travelings.
In consideration of it, being configured to stop in the Vehicular system of main vehicle 11 according to the control device 19 of the present embodiment Period starts the temperature of driving battery 15 and monitoring driving battery 15 with predetermined period (for example, several times) automatically.Work as control device 19 detect that control device 19 operates heater 72 when the temperature of battery 15 being driven to be less than predetermined start temperature Tst, until driving The temperature of battery 15 is restored to preset target temperature Ttag (Ttag>Tst).Therefore, driving battery 15 is heated by heater 72, and And the excessive reduction of the temperature of battery 15 is driven to be suppressed.
During Vehicular system stops, engine 16A stops, and the first MG 16B cannot generate electricity.Therefore, it can supply Amount of power to heater 72 is restricted to be maintained at boosting battery 70 and drives the amount of power in battery 15.Therefore, in vehicle System sets the mode (mode of setting start temperature Tst and target temperature Ttag) of the operation mode of heater 72 during stopping Significantly affect driving battery 15 of the user when taking main vehicle 11 next time outputs and inputs performance.
Specifically, for example, when start temperature Tst and target temperature Ttag is set to (to fill close to suitable temperature Point ensure to drive the temperature for outputting and inputting performance of battery 15) level when, drive the temperature 15 of battery may remain in and connect The level of nearly suitable temperature.However, the power consumption of heater 72 increases, and the 72 manipulable period of heater shortens. Therefore, when the stop period of main vehicle 11 is shorter, can substantially ensure driving battery 15 outputs and inputs performance.So And when the stop period of main vehicle 11 is long, the power supply of heater 72 is cut off, and drives the temperature of battery 15 It cannot rise.Therefore, the performance that outputs and inputs of driving battery 15 may not be able to be substantially ensured.
When start temperature Tst and target temperature Ttag are set to the substantially less than temperature of suitable temperature, heater 72 Power consumption reduce, and may insure the long duration that heater 72 can be operated.However, the temperature of driving battery 15 is protected It holds at a temperature of substantially less than suitable temperature.Therefore, when the stop period of main vehicle 11 is long, the temperature of battery 15 is driven Degree can continuously rise to driving 15 uncongealable degree of battery, but cannot fully ensure the input of driving battery 15 And output performance.
In consideration of it, according to the control device 19 of the main vehicle 11 of the present embodiment using in the peripheral region of main vehicle 11 The temperature history (hereinafter referred to as " independent information ") of the driving battery 15 detected in main vehicle 11 in domain, and in cloud service Both ambient temperature datas (hereinafter referred to as " server info ") of the peripheral region for the main vehicle 11 collected in device 30 judges The necessity of the temperature of driving battery 15 is increased during system stops.Specifically, the control device 19 of main vehicle 11 uses Independent information judges to increase the necessity of the temperature of driving battery 15 during system stops, and uses server info Judge the necessity of the temperature of raising driving battery 15 during system stops.The control device 19 of main vehicle 11 is by according to two A judgement result system stop during selection driving battery heating control model and system stop during optionally switch The operation mode of heater 72.
Fig. 3 is flow chart, and the flow diagrams illustrate work as the control device 19 according to the main vehicle 11 of the present embodiment in system One example of the processing routine executed when selection driving battery heating control model during stopping.In the operation of control device 19 Period repeats the flow chart with the scheduled period.Fig. 3 shows the processing of the control device 19 of main vehicle 11 and is taken by cloud The processing that business device 30 (managing device 32) executes.
The control device 19 of main vehicle 11 sends ambient temperature data request signal (step S10) to Cloud Server 30.Ring Border temperature data request signal is to ask Cloud Server 30 by the environment temperature number of the peripheral region of the current location of main vehicle 11 According to (environment temperature history or with environment temperature have correlation information history) be sent to the signal of main vehicle 11.Environment temperature Degrees of data request signal includes the current location etc. for specifying the vehicle identification information of main vehicle 11, main vehicle 11.
When Cloud Server 30 receives ambient temperature data request signal from main vehicle 11, the extraction of Cloud Server 30 includes Ambient temperature data in the peripheral region of the current location of main vehicle 11 in ambient temperature data request signal, and from Database 33 collects ambient temperature data (step S100).The ambient temperature data collected by Cloud Server 30 may include from master The historical information for the environment temperature that vehicle 10 in the peripheral region of the current location of vehicle 11 receives, or may include from all As internet network acquire main vehicle 11 current location peripheral region in environment temperature historical information.
The ambient temperature data being collected into is sent to main vehicle 11 (step S102) by Cloud Server 30.
The control device 19 of main vehicle 11 receives ambient temperature data (step S12) from Cloud Server 30.
The control device 19 of main vehicle 11 is come using the ambient temperature data (server info) received in step s 12 Judge whether the peripheral region of the current location of main vehicle 11 is extremely low temperature region (step S14).The judgement is using service Device information come judge system stop during increase driving battery 15 temperature necessity processing.For example, working as from cloud service When the ambient temperature data that device 30 receives includes the environment temperature less than or equal to predetermined value, the control device 19 of main vehicle 11 is sentenced It is extremely low temperature region (needing to increase the temperature of driving battery 15) to determine peripheral region.
When the control device 19 of main vehicle 11 judges that peripheral region is not extremely low temperature region (step S14 in step S14 In be "No") when, the control device 19 of main vehicle 11 is by using in the main vehicle 11 in the peripheral region by main vehicle 11 The temperature history (independent information) of the driving battery 15 that monitoring unit 15A is detected determines whether the history there are extremely low temperature (step S16).The judgement is to judge to increase necessity of the temperature of driving battery 15 during system stops using independent information The processing of property.For example, when the driving detected by the monitoring unit 15A in the main vehicle 11 in the peripheral region of main vehicle 11 When the temperature history of battery 15 includes the temperature less than or equal to predetermined value, there are extremely low for the judgement of control device 19 of main vehicle 11 The history of temperature (temperature of driving battery 15 needs to increase).
When the control device 19 of main vehicle 11 judges that the history there is no extremely low temperature (is in step S16 in step s 16 "No") when, the control device 19 of main vehicle 11 selects " usual heating mode " as the driving battery liter during system stops Warm control model (step S18).Therefore, during system stops, driving the temperature of battery usual heating mode (below with reference to Described in Fig. 4) under increase.
(it is in step S16 when the control device 19 of main vehicle 11 judges that there are the history of extremely low temperature in step s 16 "Yes") when, the control device 19 of main vehicle 11 selects " the first extremely low temperature pattern " as the driving electricity during system stops Heat up control model (step S20) in pond.Therefore, during system stops, driving the temperature of battery 15 in the first extremely low temperature mould It is increased under formula (described in Fig. 4).
When control device 19 judges that peripheral region is extremely low temperature region (being "Yes" in step S14) in step S14, The control device 19 of main vehicle 11 selects " the second extremely low temperature pattern " as the driving battery heating control during system stops Molding formula (step S22).Therefore, during system stops, the temperature of driving battery 15 (is hereafter joined in the second extremely low temperature pattern Examine described in Fig. 4) under increase.
Fig. 4 is shown in usual heating mode and extremely low temperature pattern (the first extremely low temperature pattern and the second extremely low temperature Pattern) under start temperature Tst, target temperature Ttag and heater operation duration an exemplary figure.
As shown in figure 4, under usual heating mode, start temperature Tst is set as initial value Tst0, and target temperature Ttag is set as initial value Ttag0 (Ttag0>Tst0).That is, when selecting usual heating mode, in system withholding period Between, when driving the temperature of battery 15 to become less than or equal to start temperature Tst0, heater 72 is operated.When driving battery 15 Temperature when being restored to target temperature Ttag0, heater 72 stops.
Under the first extremely low temperature pattern, start temperature Tst is set at less than the predetermined value Tst1 of initial value Tst0.Target Temperature Ttag is set at less than the predetermined value Ttag1 of initial value Ttag0.Under the second extremely low temperature pattern, start temperature Tst is set It is set to the predetermined value Tst2 less than predetermined value Tst1.Target temperature Ttag is set at less than the predetermined value of predetermined value Ttag1 Ttag2。
This setting is so that when selecting extremely low temperature pattern (the first extremely low temperature pattern or the second extremely low temperature pattern) The temperature of driving battery 15 value low when being maintained at than selecting usual heating mode.However, when selecting extremely low temperature pattern Heater operation duration H1, H2 become than the heater operation duration H0 long when selecting usual heating mode. Low value when the temperature of the driving battery 15 when the second extremely low temperature pattern being selected to be maintained at than the first extremely low temperature pattern of selection. However, select heater operation duration H2 when the second extremely low temperature pattern become than select the first extremely low temperature mould Heater operation duration H1 long when formula.
When the control device 19 of main vehicle 11 is judged by using server info around the current location of main vehicle 11 When region is extremely low temperature region (needing to increase the temperature of driving battery 15), the control device 19 of main vehicle 11 judges in system The possibility for driving battery 15 to have extremely low temperature during stopping is higher, and selects the second extremely low temperature pattern.In the second pole Under low temperature pattern, drives the target temperature Ttag2 ratios of battery 15 low under other patterns, but may insure longest heating Device operation duration H2.Thus, for example, even if when main vehicle 11 rests on extremely low temperature region singularly, can also compare Usually for longer periods inhibit freezing for driving battery 15.It therefore, can be to avoid driving when user takes main vehicle 11 next time The case where battery 15 is frozen and cannot use.
Even if the control device 19 when main vehicle 11 judges that peripheral region is not extremely low temperature by using server info When region, when the control device 19 of main vehicle 11 judges that there are the history of extremely low temperature (driving batteries by using independent information 15 temperature needs to increase) when, the control device 19 of main vehicle 11 drives battery 15 to have also by consideration during system stops There is the possibility of extremely low temperature and selects the first extremely low temperature pattern.The target temperature Ttag1 high of first extremely low temperature pattern In the target temperature Ttag2 of the second extremely low temperature pattern.Therefore, although the heater operation of the first extremely low temperature pattern continues Between H1 it is shorter than the heater operation duration H2 of the second extremely low temperature pattern, but drive battery 15 temperature in the first extremely low temperature It may remain in higher value under degree pattern.Thus, for example, when user is commuted using main vehicle 11 from family in (when with Family take main vehicle 11 next time before period it is shorter when), can fully ensure driving battery 15 outputting and inputting property Energy (electric vehicle driving performance).
As described above, independent information and server info are used according to the control device 19 of the main vehicle 11 of the present embodiment, To judge to increase the necessity of the temperature of driving battery 15 during system stops.Therefore, with when use independent information and service It is compared when one in device information, can more accurately judge the necessity for increasing the temperature of driving battery 15.Main vehicle 11 Control device 19 during system stopping by selecting driving battery heating control model according to two judgement results in system The operation mode of optionally switch heater 72 during stopping.Therefore, considering independent information and server both information In the case of, by properly selecting the operation mode of heater 72, the temperature of driving battery 15 can be increased.Therefore, Ke Yishi Locality increases the temperature of driving battery 15.
Particularly, when the control device 19 of the main vehicle 11 according to the present embodiment judges needs by using server info When increasing the temperature of driving battery 15, the judgement driving battery 15 of control device 19 of main vehicle 11 has pole during system stops The possibility of low temperature is higher, and selects the second extremely low temperature pattern, has more lower than the first extremely low temperature pattern Target temperature but longer heater operation duration.Thus, for example, even if when main vehicle 11 rest on singularly it is extremely low It, can also be than usually for longer periods inhibiting freezing for driving battery 15 when temperature region.Therefore, when user takes main vehicle next time It, can be frozen to avoid driving battery 15 and the case where cannot use when 11.
Even if the control device 19 when main vehicle 11 judges that the temperature of driving battery 15 is not required to by using server info When increasing, when the control device 19 of main vehicle 11 judges that the temperature of driving battery 15 needs to increase by using independent information When, according to the control device 19 of the main vehicle 11 of the present embodiment, also by consideration, the driving battery 15 during system stops has pole The possibility of low temperature and select that there is the heater operation duration more shorter than the second extremely low temperature pattern but higher Target temperature the first extremely low temperature pattern.Thus, for example, even if when user is commuted using main vehicle 11 from family in When, the level of enough electric automobile during traveling performances is also ensured.
Driving battery cooling control before charging
For example, when the user of main vehicle 11 goes out to return home, driving battery 15 may be located due to the traveling of outgoing period In the condition of high temperature.When executing external charging in this state, driving battery 15 is due to the heat that charging generates and in height Temperature state, and battery 15 is driven to may deteriorate.In particular, when driving battery 15 is in the condition of high temperature and drives battery 15 When external charging increases, driving battery 15 may be deteriorated quickly state-of-charge (SOC).
In consideration of it, cooling before external charging according to the judgement of the control device 19 of the main vehicle 11 of the present embodiment Drive the necessity of battery 15.When the control device 19 of main vehicle 11 judgement driving battery 15 needs cooled, main vehicle 11 Control device 19 cooling " before charging of battery 15 of driving is executed by operating cooling fan 73 before executing external charging Cooling control ".
During judgement necessity of cooling driving battery 15 before external charging, the control device of main vehicle 11 19 are used in a manner of identical in the necessity of the temperature of judgement raising driving battery 15 in the peripheral region of main vehicle 11 In main vehicle 11 in the temperature history (independent information) of driving battery 15 that detects and collected in Cloud Server 30 Both ambient temperature datas (server info) of the peripheral region of main vehicle 11.
Specifically, the control device 19 of main vehicle 11 judges the cooling driving before external charging using independent information The necessity of battery 15, and judge the cooling necessity for driving battery 15 before external charging using server info. The control device 19 of main vehicle 11 determines whether to execute cooling control before charging according to the two judgement results.
Fig. 5 is flow chart, and the flow diagrams illustrate be when the judgement of control device 19 of the main vehicle 11 according to the present embodiment A no example for executing the processing routine executed when the preceding cooling of charging controls.In Figure 5, with identical as step shown in Fig. 3 Reference numeral be described the step of instruction, and here will not be described in detail.
The control device 19 of main vehicle 11 judges whether external charging is requested (step S30).For example, when in supply of electric power User executes for starting the outside on power supply facility 41 in the case that the connector 42 of facility 41 is connected to entrance 13 When the operation of charging, the control device 19 of main vehicle 11 judges that external charging is requested.
(it is in step S30 when the control device 19 of main vehicle 11 judges that external charging is not requested in step s 30 "No") when, the control device 19 of main vehicle 11 skips forward processing and is transferred to return.
When the control device 19 of main vehicle 11 judges that external charging is requested (being "Yes" in step S30) in step s 30 When, the control device 19 of main vehicle 11 is judged using the ambient temperature data (server info) received in step s 12 Whether the peripheral region of the current location of main vehicle 11 is very hot region (step S32).The judgement is using server info Judge the processing of the necessity of cooling driving battery 15 before external charging.For example, when the environment received from Cloud Server 30 When temperature data includes the environment temperature more than or equal to predetermined value, the control device 19 of main vehicle 11 judges that peripheral region is pole Thermal region (driving battery 15 needs cooled).
When the control device 19 of main vehicle 11 judges that peripheral region is not that very hot region (is in step S32 in step s 32 "No") when, the control device 19 of main vehicle 11 is by using the monitoring in the main vehicle 11 in the peripheral region by main vehicle 11 Whether the temperature history (independent information) for the driving battery 15 that unit 15A is detected is big to judge to drive the temperature of battery 15 to have In or equal to predetermined value history (step S36).The judgement is to judge the cooling drive before external charging using independent information The processing of the necessity of dynamic battery 15.
When the control device 19 of main vehicle 11 judges that peripheral region is that very hot region (is in step S32 in step s 32 "Yes") when, or when the control device 19 of main vehicle 11 judges that driving the temperature of battery 15 to have is more than or waits in step S36 When history (being "Yes" in step S36) of predetermined value, the control device 19 of main vehicle 11 executes cooling control (step before charging S34).After executing preceding cooling of charging and controlling, the control device 19 of main vehicle 11 executes external charging.
When the control device 19 of main vehicle 11 judges that peripheral region is not that very hot region (is in step S32 in step s 32 "No") when, and judge to drive the temperature of battery 15 without being more than in step S36 when the control device 19 of main vehicle 11 or Equal to predetermined value history (in step S36 be "No") when, the control device 19 of main vehicle 11 does not execute cooling control before charging (step S38).That is, outside the control device 19 of main vehicle 11 executes in the case of cooling control before not executing charging Charging.
As described above, independent information and server info are used according to the control device 19 of the main vehicle 11 of the present embodiment, To judge the necessity of the cooling driving battery 15 before external charging.Therefore, with when use independent information and server info In one when compare, can more accurately judge the necessity of cooling driving battery 15.The control device 19 of main vehicle 11 is logical It crosses and chooses whether that cooling control is come the operation mould of optionally switch cooling fan 73 before executing charging according to two judgement results Formula (operation stops).Therefore, in the case where considering independent information and server both information, by properly selecting cooling The operation mode of fan 73 can cool down driving battery 15.Therefore, driving battery 15 before charge can be by suitably cold But.
Modified example 1
Temperature adjustment device (heater 72 and cooling fan of the switching for driving battery 15 shown in Fig. 3 and Fig. 5 73) technology of operation mode is for the purpose of illustration, rather than restrictive.
The technology of the operation mode of switching heater 72 is shown in FIG. 3 so that when the control device 19 of main vehicle 11 When judging that the temperature of driving battery 15 needs to increase by using independent information, the control device 19 of main vehicle 11 selects the first pole Low temperature pattern, and when the control device 19 of main vehicle 11 judges that the temperature of driving battery 15 needs by using server info When increasing, the control device 19 of main vehicle 11 selects the second extremely low temperature pattern.
However, for example, when an instruction in independent information and server info needs to increase the temperature for driving battery 15 When, the control device 19 of main vehicle 11 can select the first extremely low temperature pattern.When independent information and server both information are equal When instruction needs to increase the temperature of driving battery 15, the control device 19 of main vehicle 11 can be determined that driving battery 15 with extremely low Temperature possibility it is higher, and select there is target temperature more lower than the first extremely low temperature pattern but longer heating Second extremely low temperature pattern of device operation duration.
Alternatively, for example, when the temperature of an instruction driving battery 15 in independent information and server info needs to rise The control device 19 of Gao Shi, main vehicle 11 can not select extremely low temperature pattern, and select usual heating mode.Work as independent information When indicating to need to increase the temperature of driving battery 15 with server info, the control device 19 of main vehicle 11 can select extremely low Temperature model (the first extremely low temperature pattern or the second extremely low temperature pattern).
The technology of the operation mode of switching cooling fan 73 is shown in FIG. 5 so that when independent information and server are believed When breath indicates that driving battery 15 needs cooled before charge, the control device 19 of main vehicle 11 executes the preceding cooling control of charging Otherwise system does not execute cooling control before charging.
However, for example, when an instruction driving battery 15 in independent information and server info needs before charge When cooled, the control device 19 of main vehicle 11 can execute cooling control before charging.When independent information indicates driving battery 15 When needing cooled before charge, when server info indicates that driving battery 15 needs cooled before charge, and When independent information and server info indicate that driving battery 15 needs cooled before charge, the operation of cooling fan 73 Pattern (operating time section, target temperature etc.) can be different.
